Derik Broadnax

For the last 10 years most people would call me a strength coach or personal trainer. My goal is to evolve into a teacher. I love working with anyone possessing a high level of intrinsic motivation to become a better human. My only rule is: you have to make progress toward your goals. If you’re making progress, keep cruising. If you’re not, try another way.

GMB Trainers Surpass Industry Standard

Most fitness systems hand out certifications like candy.

All you need is a free weekend and a couple thousand dollars, and you too can be a fitness expert – Wow!

We decided not to go down that path. Instead, we set out to improve on the certification process in the most fundamental way by replacing the “certification seminar” with a minimum of three months of apprenticeship.

It’s a much more time-consuming process for us and for our trainer candidates, but the result is that we can recommend the individuals on this page with pride.
